Offhand that makes me suspicious of the jug gust chain. I’m not sure how often that would come up though. Maybe just in vim. One shortcut for finding words that end in phonemes I’ve already tested, is to find words with the exact same ending sound as another word in the alphabet, but with a sufficiently distinct starting phoneme.
Something to consider: replacing 'jury' with 'jug' (or some other one-syllabic phoneme) might increase overall efficiency, even if one or two combinations need a slight pause.
